Aromatherapy:
For years, aromatherapy has been touted as a safe and natural way to relax and even heal. Essential oils from a variety of scents have been added to candles and sprays to help people feel better. However, a recent study performed at Ohio State University says that these smells, as nice as they may be, do not do a thing to improve people’s health.
To find out if aromatherapy actually works, the researchers tested two of the most popular scents: lemon and lavender. First, test subjects had their heart rate, blood pressure, stress hormones, and immune function measured and noted. Next, they were subjected to mild stressors and then told to sniff one of the scents to see if the scent would help them to relax. Finally, all the subjects were tested again to look for improvement. No significant changes were noted—even in people who had previously stated they were true believers in the power of aromatherapy.
Of course, this does not necessarily prove that aromatherapy is worthless, either. It was just one small study, pitted against the opinions of thousands of consumers who swear by peppermint on their pillow for an upset stomach or vanilla for a headache. More tests will be done, but in the meantime, a whiff of lavender, lemon, or other scents will certainly do no harm—and can be quite pleasant at the same time.

SUNLIGHT:
Most people are familiar with the damaging effects of the sun on unprotected skin, but not enough attention is paid to the many positive effects of receiving direct exposure to sunlight on a regular basis. The most compelling argument for increased exposure to sunlight is the need for vitamin D in the human body. Vitamin D is integral for maintaining healthy bones and preventing diseases like rickets and osteoporosis. It is synthesized by the skin when it comes into contact with the UVB rays found in sunlight. In order to ensure you are receiving the proper amount of vitamin D, it is recommended to get 15 minutes of direct exposure to sunlight at least two or three times a week. UVB rays are made less intense when passing through clouds and pollution, and they will not transmit through glass or sunscreen. UVB rays are also less effective the farther you are from the equator. People with darker skin require more exposure to the sun to receive the same amount of vitamin D.
In addition to vitamin D, sunlight will help regulate the circadian rhythms that ensure you get a good night’s sleep. Sunlight helps to prevent an overactive immune system, which may prove useful in preventing autoimmune diseases like psoriasis and lupus. Recent studies have even shown that sunlight can help lessen the symptoms of Alzheimer’s disease. The negative impacts of excess exposure to sunlight should not be ignored; cancers resulting from skin damage are a real concern that must be taken seriously. But the importance of vitamin D and the other positive impacts of sunlight make a compelling argument for making sure we are spending enough time every week in direct sunlight.
What is the main idea of the passage about Sunny-Side Up?
- A. There are many positive effects of receiving direct exposure to sunlight.
- B. The negative impacts of sunlight should not be ignored.
- C. Vitamin D is integral for maintaining healthy bones and preventing diseases.
- D. Vitamin D is synthesized by our bodies in reaction to direct sunlight.
Correct Answer: A
Rationale: The passage discusses the positive effects of sunlight, including vitamin D synthesis.
Barefoot Running:
Barefoot running is a rapidly growing movement that encourages people to leave their shoes at home and take to the streets in only their bare feet. Barefoot running advocates are quick to point out that while shoe technology has advanced significantly since the advent of the modern running shoe, there has been little decline in the number of injuries that occur from running. Humankind has been running for millions of years, and modern running shoes have existed for less than 50 years. By wearing larger shoes with excessive cushioning, we are changing the biomechanics of how we run, thereby increasing the likelihood for injury.
Early humans ran with a “forefoot strike,” landing closer to the balls of their feet and using their foot’s natural arch as a spring to store and release energy. Modern shoe designs encourage a “heel strike,” landing on the heel and rolling forward to the toe. Barefoot running advocates believe “heel striking” replaces your reliance on the natural mechanics of your feet with the cushioning provided by your shoes, and that this is what causes many of the injuries affecting runners today.
Critics assert that while our feet may have been designed for barefoot running, our road surfaces were not. Concrete and asphalt are much firmer than any surface where our human ancestors would have been running. Broken glass and debris also may make barefoot running a significant challenge. There is little consensus when it comes to the safety and effectiveness of barefoot running, but even the most skeptical of podiatrists will agree that wearing heavily padded shoes too often can result in a weaker foot and leg structure. Spend some extra time walking barefoot around your house; aside from building up the muscles and tendons that strengthen your feet, you may just find yourself tempted to go for a run.
Which of the following statements is an opinion related to Barefoot Running?
- A. Running barefoot is natural and advantageous.
- B. The cost of modern running shoes keeps increasing.
- C. Concrete sidewalks are harder than dirt paths.
- D. The arch of the foot gives a spring to the step.
Correct Answer: A
Rationale: This is an opinion that cannot be objectively verified.

Correct Answer: D
Rationale: Consensus in this context refers to unanimity, meaning a general agreement among people.
SUPER FOODS:
Super foods are whole, unprocessed foods such as blueberries, walnuts, beans, oats, and broccoli. Spinach, yogurt, and pomegranates are also considered super foods. They are classified as such because they contain high levels of essential nutrients, are low in calories, and can often help prevent—and even reverse—some of the common effects of aging including cardiovascular disease, type 2 diabetes, high blood pressure, and certain types of cancer. Super foods help lower cholesterol levels in the blood and, some researchers believe, even improve a person’s mood.
High on the list of super foods are blueberries, fresh or frozen, which are loaded with vitamin C, antioxidants, and potassium. Blueberries are also an anti-inflammatory, which many researchers and nutritionists believe is beneficial. Lentils are a super food that helps prevent a spike in insulin levels that can increase body fat. Lentils are high in both fiber and protein, each of which contributes to stabilizing blood sugar levels and reducing excess fat, especially in the stomach area. Walnuts are a plant-based source of essential unsaturated omega-3 fatty acids, which can improve cholesterol and lower the risk of heart disease by as much as 50 percent.
All oats are healthful. Oats, even instant oatmeal, are digested slowly while providing up to five grams of fiber per serving. As physicians and nutritionists continue to study super foods and their effects, consumers continue to educate themselves about the variety of benefits. In an era when consumers question the origin and nutritional value of much of the food on store shelves, super foods are some of the most healthful and natural whole foods available.
Which statement would not be inferred by the reader in the passage about Super Foods?
- A. Instant oatmeal can be part of a healthful breakfast.
- B. Blueberries are an especially healthful food.
- C. Certain grains and dairy products are super foods.
- D. Super foods are more expensive than processed foods.
Correct Answer: D
Rationale: The passage does not suggest that super foods are more expensive than processed foods.
SLEEP:
Developing muscle growth is an effective way to stay healthy as we get older, but many people find it difficult to develop this muscle growth, even after modifying their exercise routine and food intake. What many people may not realize is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The hard work of developing muscle is done in the gym, on a track, or on the court, but the actual growth takes place during the rest periods that follow a workout. Your body immediately begins rebuilding the muscle fibers that were broken down during the course of your workout. Much of this process is carried out while you are sleeping, so without a full night of sleep, muscle fibers will not have the opportunity to rebuild.
Human growth hormone (HGH) is an amino acid that is central to regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. The amount of HGH in your body spikes significantly during deep sleep, which makes getting at least 7 to 10 hours of sleep every night imperative to anyone hoping to develop additional muscle growth. Recent studies have linked inadequate amounts of sleep to lowered levels of leptin, a hormone in the brain that controls appetite. Test subjects who received less sleep, or frequently interrupted sleep, would crave carbohydrates even after their caloric needs reached satiety. This can contribute to obesity and negatively affect any good habits people may have developed with regard to food intake.
What conclusion can the reader draw after reading the passage about The Sleep Workout?
- A. Getting uninterrupted sleep is more important than getting enough sleep.
- B. Insufficient sleep may result in an increased risk for obesity.
- C. Human growth hormone is not essential for muscle development.
- D. Leptin is essential for building muscle.
Correct Answer: B
Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.
